West made half of his 12 3-point shots and added seven rebounds and seven assists.
Senior guard Shamir Davis contributed 15 points, six assists and four steals while sophomore forward Marvin Frazier had 10 points, five rebounds and two blocked shots.
The Demons played late Wednesday night against Victoria Select, and will have a rematch with the same team in their final game north of the border Thursday evening.
In Tuesday’s triumph, NSU opened a 29-21 first-quarter lead but VIU tightened it to 45-39 at halftime.
The Demons outscored their hosts 30-14 in the third quarter to take command.
The VIU Mariners were led by a game-high 20 points from senior forward Greg Gillies, and 14 by guard Jon Bethell.
Brent Dunlop, the sports information director for Vancouver Island, said the home crowd enjoyed watching the Demons.
Davis, interviewed postgame by Greg Sakaki of the Namaimo News Bulletin, said the Demons got a lot out of the contest.
“VIU was very good. They played very good, they had a good crowd, everyone came out and supported them,” said Davis. “They gave us a good test early. We needed to run like this.
“Regardless of the opponent or the level of play, we still want to win, that’s the main priority,” Davis said. “Any gym you go into, you want to win.”
Playing under international rules led to a more physical style of play than NSU typically encounters, which Davis said was beneficial.
